Japan's cities are well visited, but what about its coast? A new small group tour of the little-known west coast is now available with Inside Japan (0870 120 5600; www.insidejapantours.com), including the two-mile sandbar known as the 'bridge of heaven', and the sand dunes, stalactites and waterfalls in the 'desert' of Tottori. The 13-night tour costs from £1,895 per person, including flights from Heathrow.
